We had a great stay at Mam's apartment. The location is great, in the modern part of Bangkok and close to the metro. Two characteristics set this flat apart : the view from the balcony and from the bedroom over the modern part of the city and its skyscrapers is fantastic, and the swimming pool is incredible. During our 48h stay, we really enjoyed it a lot.
Aside from that, everything was great : efficient and friendly communication with Mam, flat not huge but very modern and spotless clean, building very secure, check-in convenient thanks to the digipad installed on the door.
The street where the building is located is not the most lively but it's not really an issue : there is a 7/11 down the building, many restaurants can be reached with a 5 to 10 mn walk, and there is even a local temple close to the subway. We recommend the address and would definitely stay here again.
